Description

[Technical field]

[0001] This invention relates to a Sierra cup for use in outdoor activities such as camping. [Background technology]

[0002] Conventionally, Sierra cups used in outdoor activities such as camping are well known. For example, Patent Document 1 discloses a Sierra cup including a cup body and a holder for holding the cup body. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Utility Model Registration No. 3237024 Summary of the Invention [Problem to be solved by the invention]

[0004] According to the Sierra Cup disclosed in Patent Document 1, even when hot food is contained within the metal cup body and the cup body itself is hot, the user can hand over or eat or drink by grasping the holder without directly touching the cup body with their hands.

[0005] However, if the holder is made of a thermally conductive material, the heat from the cup body can be transferred to the holder, making it difficult to hold the cup in one's hands, or children or infants can accidentally touch the hot holder body and be burned.

[0006] Furthermore, if the cup body is made of a metal such as aluminum or copper, it may give an impression of being inorganic and lacking in artificial warmth.

[0007] To provide a Sierra cup which is an improvement of a conventional Sierra cup and which prevents a user from getting burned even if the user directly touches the cup body and gives a warm impression by using natural materials. [Means for solving the problem]

[0008] In order to solve the above problems, the present invention is directed to a Sierra cup comprising a cup body and a holder that is detachably attached to the cup body, the cup body being made of wood. Effect of the Invention

[0009] The Sierra cup of the present invention comprises a cup body and a holder that can be detachably attached to the cup body. Since the cup body is made of wood, users can touch the cup body directly without getting burned, and the cup gives a warm impression due to the use of natural materials.

[0011] 1 to 3, a Sierra cup 10 according to the present invention has a vertical direction Y, and includes a wooden cup body 20 and a holder 30 that is detachably attached to the cup body 20.

[0012] The cup body 20 has a circumferential direction L, a flange-shaped rim portion 21 forming an upper edge portion, a bottom surface 22, and a peripheral wall portion 23 extending in the circumferential direction L between the rim portion 21 and the bottom surface 22. The cup body 20 also has drinking spout recesses 26A, 26B located on the upper edge side and positioned radially opposite each other.

[0013] Decorative elements 24, 25 consisting of a product brand name, brand logo, etc. are arranged on the inner and outer surfaces of the bottom surface 22 of the cup body 20. In addition, as shown in the figure, a groove 28 extending discontinuously in the circumferential direction L is located between the rim portion 21 and the peripheral wall portion 23 of the cup body 20.

[0014] The cup body 20 is made of wood having non-thermal conductivity, and its raw material may suitably be cypress, cedar, bamboo, rubberwood, pine, Japanese cypress, or other wood.

[0015] Since the cup body 20 is made of wood, even if high-temperature contents such as hot coffee or soup are placed inside, the cup body 20 itself does not become excessively hot, and even if it becomes too hot to hold in the hand, or if an infant or child accidentally touches the cup body 20 directly, there is no risk of being burned.

[0016] Furthermore, if the cup body 20 were made of metal, it would give an impression of being inorganic and artificial, lacking warmth, but by using wood, it can give an impression of using natural materials, and therefore has an appearance suitable for natural places such as campsites.

[0017] In addition, since the pair of drinking spout recesses 26A, 26B are located on the rim 21 of the cup body 20 and a part of the peripheral wall 23 adjacent thereto, the user can drink the contents such as hot coffee or soup without spilling them by placing his / her lips against either of the drinking spout recesses 26A, 26B. Since the pair of drinking spout recesses 26A, 26B are located in a direction intersecting with the holder 30, the user can drink the contents by simply placing his / her lips against them while holding the holder 30.

[0018] The holder 30 has a holding portion 31 having an annular shape in a plan view, and a gripping portion 32 connected to the holding portion 31. The gripping portion 32 has a pair of extending portions 33A, 33B positioned opposite each other in the radial direction and extending from the holding portion 31 in a bent and upwardly convex manner, and a connecting portion 34 connecting the pair of extending portions 33A, 33B. The extending portions 33A, 33B have a first portion 41 extending radially outward from the holding portion 31, a second portion 42 that bends upwardly from the first portion 41 and gradually curves radially inward as it extends further downward, and a third portion 43 that bends from the second portion and extends further radially inward to connect to the connecting portion 34.

[0019] Because the gripping portion 32 of the holder 30 has such a shape, when a user holds the cup by inserting his / her index finger (or middle finger) while placing his / her thumb on the gripping portion, a sufficient space is formed between the cup body 20 and the index finger, and the index finger does not hit the cup body 20 when inserted. Also, because the second portion 42 of the extensions 33A, 33B has a shape that curves toward the cup body 20, and the third portion 43 has a bent shape, the extensions 33A, 33B are positioned to surround the index finger, and even if the thumb is suddenly released from the gripping portion 32, the gripping portion 32 will not come off the index finger and the Sierra cup 10 will not fall.

[0020] The holder 30 can be made of a flexible plastic or metal material, such as polypropylene, ABS, silicone rubber, or aluminum.

[0021] 5(a) and (b), the holder 30 is detachably attached to the cup body 20 by engaging the holding portion 31 of the holder 30 with the groove 28 of the cup body 20. The cup body 20 is formed so that the dimension in the circumferential direction L decreases from the upper edge toward the bottom surface 22, and the inner diameter dimension of the holding portion 31 of the holder 30 is larger than the outer diameter dimension of the bottom surface 22 and is approximately the same as the outer diameter dimension in the vicinity of the rim portion 21.

[0022] Therefore, when attaching the holding portion 31 of the holder 30 to the cup body 20, as shown by the arrow K in Fig. 3, the holding portion 31 is brought closer to the bottom surface 22 of the cup body 20, and the portion of the cup body 20 on the bottom surface 22 side is inserted into the holding portion 31. When the holding portion 31 is moved upward in this state, since the inner diameter dimension of the holding portion 31 is approximately the same as the outer diameter dimension in the vicinity of the rim portion 21, the holding portion 31 flexibly deforms and moves upward while being pushed out so that its inner diameter dimension increases, and engages with the groove 28. As a result, the cup body 20 is held in a state where it is clamped by the holding portion 31 of the holder 30.

[0023] The rim portion 21, which protrudes further outward from the peripheral wall, is located above the groove 28, thereby preventing the holding portion 31 of the holder 30 from moving upward. Also, because the holding portion 31 of the holder 30 is held in the groove 28 in a flexibly deformed and expanded state, even if it receives an external shock during use, it will easily move downward, preventing the holder 30 from accidentally coming off the cup body 20 and causing the cup body to fall.

[0024] On the other hand, when a user grasps the gripping portion 32 of the holder 30 and pulls downward with a relatively strong force, the holding portion 31 moves while sliding along the peripheral wall portion 23 of the cup body 20, and the holder 30 can be removed from the cup body 20. Since the holder 30 is thus detachably attached to the cup body 20, for example, when either the cup body 20 or the holder 30 deteriorates due to use, only one of them can be replaced and the other can be reused, which is economical.

[0025] Furthermore, when storing multiple Sierra cups 10, compact storage can be achieved by removing the holder 30 from the cup body 20 and stacking the multiple cup bodies 20 one on top of the other.

[0026] 4(a) to 4(c), the groove 28 extends discontinuously in the circumferential direction L and has both ends 28a, 28b, with a flat portion 29 where the groove 28 is not formed being located between the both ends 28a, 28b. The flat portion 29 is located opposite the gripping portion 32 of the holder 30. The cup body 20 is made of wood and is therefore more likely to crack than one made of metal. For example, if the groove 28, which is a thin portion, extends continuously in the circumferential direction L, cracks are likely to occur along the groove 28. However, by forming the flat portion 29 and having the groove 28 extend discontinuously in the circumferential direction L, it is possible to suppress the occurrence of cracks in the circumferential direction L.

[0027] Depending on the situation and purpose of using the Sierra cup 10, a cup body 20 with a design different from that shown in the drawings can be freely selected and used. Furthermore, since the cup body 20 is made of wood, it can be used by directly holding the cup body 20 without the holder 30.

[0028] The present invention may include at least the following embodiments, which may be adopted separately or in combination with each other.

[0029] (1) The cup body has a flange-shaped rim portion that forms a circumferential and radial upper edge portion, a bottom surface, and a peripheral wall portion that extends circumferentially between the rim portion and the bottom surface, and the holder has an annular retaining portion and a gripping portion that are attached to the cup body, and between the rim portion and the peripheral wall portion of the cup body is a groove that extends discontinuously in the circumferential direction and into which the retaining portion of the holder engages. (2) A pair of drinking spout recesses are located in the rim portion of the cup body and in a portion of the peripheral wall portion adjacent thereto. (3) The gripping portion has a pair of extending portions positioned opposite each other in the radial direction and extending from the holding portion in a bent and upwardly convex manner, and a connecting portion connecting the pair of extending portions, and the extending portions have a first portion extending outward in the radial direction from the holding portion, a second portion bending upward from the first portion and gradually curving inward in the radial direction as it extends further downward, and a third portion bending from the second portion and extending further inward in the radial direction to connect with the connecting portion.
